// @description The first version of this script ("Google Bookmark Enhacements") was originally written by Daniel Cormier. I removed some features and added a lot own stuff. This script manipulates the Google Bookmarks page (google.*/bookmarks) so that you can navigate through labels much better. In the navigation bar on the left are now only labels, that label at least one bookmark in the search result. That means that only the relevant labels are visible. You have also Plus-links next to the label name, that imitate a folder structure a little bit. You'll have to check it out for yourself.
